Wash all the jars, bands, and lids in hot soapy water. Prepare the water bath and bring to a boil.
In a saucepan, bring the vinegar and wine to a slow simmer, do not boil.
Place the smashed cloves, red onion slices, basil leaves, and peppercorns into the jars.
Fill the jars with the tomatoes and put 1/2 tsp of canning salt into each.
Pour the vinegar/pinot noir into the jars. Using the bubble popper, remove any trapped air. Top off each jar so that there is 1/2-inch headspace.
Wipe the rims of the jars with a clean, dry paper towel. Place the lids and bands onto the jars and tighten.
Place the jars into the water bath, cover, and process for 35 minutes.
Once the jars are finished, turn off the heat, remove the lid, and remove the jars to a towel lined cutting board. Allow to rest for 12 hours before labeling and dating. If any jars do not seal, they should be refrigerated and used first.
